From reducing wrinkles to fading acne, red light therapy is a promising treatment for various skin problems and other conditions as well. Find out how red light works, what you can treat with it, and how safe this therapy is.
Red light therapy was originally tested by NASA to stimulate plant growth in space and help heal astronauts’ injuries. Later, potential uses were investigated and expanded.
Currently, this therapy is used to treat a wide range of conditions, but not all uses are scientifically supported. Published studies to date indicate potential for certain conditions, but more research is needed to confirm its effectiveness.

Red light therapy is still an emerging treatment that is attracting more and more interest, say specialists at the academic medical center Cleveland Clinicfrom the USA.
How does red light therapy work?
This therapy uses visible light from the red spectrum (620-700 nm) that penetrates the skin at a superficial depth of 5-10 millimeters. Red light is believed to act on mitochondria, considered the “powerhouses” of cells, and stimulate cellular energy production.
Cells can work more efficiently with more energy. It accelerates the processes of repairing the skin, stimulating the growth of new cells and regenerating this tissue. More precisely, certain cells absorb wavelengths of light and are stimulated to work better.
Potential skin health benefits include:
- stimulating the production of collagen, the proteins that give the skin structure, strength and elasticity;
- increased production of fibroblasts, the cells that produce collagen and make up connective tissue;
- improvement of blood circulation in the tissues;
- reducing inflammation at the cellular level.
Red light therapy is different from infrared. Light from the infrared spectrum, invisible to the human eye, penetrates deeper into tissues, up to 2-5 cm. Infrared therapy is used in sports medicine, physiotherapy and rehabilitation to alleviate muscle and joint pain and deep inflammation.
What are the uses of red light therapy?
Red light therapy is touted as a treatment for several common skin conditions:
- reducing wrinkles, fine lines and age spots;
- reduction of stretch marks;
- alleviation of psoriasis, rosacea and eczema;
- reducing acne;
- acceleration of wound healing;
- improving the appearance of scars;
- fading of red or dark spots;
- restoring the skin affected by sun exposure;
- stimulating hair growth in people with androgenetic alopecia.
At the same time, red light is used in photodynamic therapy. This procedure involves the administration of light-sensitive drugs (photosensitizing agents) and a red or blue light source. The light activates the drug and generates a chemical reaction inside the abnormal cells that leads to their destruction.
Photodynamic therapy has a wide variety of uses, with good results in:
- acne vulgaris;
- warts;
- psoriasis;
- certain types of skin cancer, such as low-risk basal cell carcinoma.
Red light therapy is being studied for several other medical uses, such as:
- Reducing the side effects of chemotherapy and radiation therapy, such as oral mucositis, an inflammation of the lining of the mouth;
- Alleviation of pain and inflammation associated with peroneal (ankle) tendinitis, rheumatoid arthritis, carpal tunnel syndrome and osteoarthritis of the knee;
- Prevention of recurrences of oral herpes caused by the herpes simplex virus.
Many other benefits of red light therapy are advertised on the internet. However, there is no scientific evidence to support its use for weight loss, treating cancer, eliminating cellulite, and combating depression or seasonal affective disorder.
How the therapy is applied
Red light therapy is carried out by exposure to various special devices, such as lamps, masks, panels, brushes or headphones for hair regeneration. The treated areas are exposed to red light for a period of time determined according to the patient’s needs. The therapy can be applied by a dermatologist or at home. Most household appliances contain LEDs that are considered safe for home use.
The red light used in dermatology clinics is stronger than that emitted by devices intended for home use, according to American Academy of Dermatology (AAD). The wavelength is longer, so the red light penetrates deeper into the skin and can reach deeper tissues. That is why the results of red light therapy applied in dermatological offices often prove faster and better.
Usually, to get the best results, dermatologists recommend red light therapy as a complementary treatment. It is part of a treatment plan that also includes standard therapies. For example, to fade wrinkles, red light is added to other treatments, such as creams with various therapeutic substances, microneedling or chemical peeling.
To be effective, exposure to red light is done several times. Depending on the problem treated, between one and three sessions per week are recommended, for several weeks or even months. Additional maintenance treatments may also be required.
How safe is red light therapy?
When used short-term and as directed, red light therapy is considered safe and is not associated with side effects. This therapy is non-toxic, invasive and as aggressive as some topical skin treatments.
Unlike ultraviolet (UV) light from the sun or tanning salons, red light has no carcinogenic potential. However, it is preferable that the therapy be carried out under the supervision of a specialist, especially in the case of people with chronic conditions or sensitivity to light.
When red light is used too frequently or without following the instructions, there is a risk of causing damage to the skin or eyes if they are not protected. The long-term safety of devices that use red light therapy is not well known.
The safest option is to discuss with a dermatologist whether this treatment is an effective and safe option for a specific dermatological problem.
